To ALL WHoM 1r MAY coNcERN.

Be it known that I, L. M. CRANE, of Bnllston Spa, jn the county of Saratoga, .State of New York, have invented a new and improved Water-Proof Paper Fabric; and I do hereby declare that the following is a full, clear, and exact description thereof, which will ena-ble others skilled in the art to make and use the same, reference being hadtothe accompanying drnwiugsfforming a part of this specification, in Which- Figure 1 is n. view of a piece of myiimproved fabric, with the layers or sheets detached or separated at one end for the purpose of showing the construction. Y i

Figure 2, a diagram designed to show the mode of manufacturing the same.

Similar letters of reference indicate like parts.

This invention relates to o. new and improved water-proof paper fabric, especially useful for the manufac-v ture of collars, bosoms, cuffs, shirts, vests, garments, covers, wrappers, and other useful purposes.

The invention consists in ,constructingl the fabric of t'\vo.or more layers of paper' with a layer or sheet or sheets vof gatta perche-0r rubber, or other water-proof material, interposed and conducted between the sheets .of paper, substantially as hereinafter fully-shown-and described.

The layers-of paper, AAB., are manufactured in the usual manner, and of any desired quality and thickness,'

according to the use for which the fabric is designed. The layer or sheetof gotta percha, C, or rubber, is interposed between the layers of paper'A B, and by heat and presspre the layers of paper and the gutta percha or rubber are firmly cemented together. 4My mode of manufactur will be clearly understood by referring to iig. 2. The layers of paper, AB, are wound upon rollers or shafts, a a, placed one above the .other at a snitP able distance apart. The layer of gatta perche or rubber, C, is wound upon a roller or shaft, b, placed between the rollers or shafts a'a, and the three layers, A C, pass between heated rollers, D D, which cause the layers to be firmly cemented together, the gatta percha or rubber, when heated, being suiiiciently adhesive to cause the layers of paper and water-proof material to unite under pressure andbecome securely attached. The gotta perche, or rubber layer, C,renders the fabric impervious to water, and materially strengthens it.V The two layersof paper, AVB, may be of diiferent quality, the outer layer, A, being, superior to the inner one, B. This would of course reduce the cost of manufacture, and, in certain cases, where the inner Alayer is not seenor is not exposed in the use of 4the article manufactured from the fabric, will answer equally as well as if both layers of paper were of superior quality. v i Y i My improvement not only renders the paper water-proof, but also makes itstronger and sti`er,` so that when my improved fabric is used for the manufactureV of collars, cuifs, bosoms, and other articles of wear to .be

worn next to the skin, it prevents the perspiration and moisture from passing through the fabric,'and the outside is thus protected from soiling. Collars made of my improved fabric are also stiffer than other paper collars, and will not so easily break down when worn. The superior strength of my improved fabric prevents it from breaking when button-holes are made, in it, and thus -facilitates its use for various kinds of light garments.

Having `thus described my invention, lclaim as new, and des-e tosecure by Letters Patent, asan improved article of manufacturep A water-proof paper fabric made substantially as herein shown and described.

' The above specification of my invention signed by me this day of August, 1866.
